Planning a trip or simply curious about the weather in San Salvador? In this section, you will find the most up-to-date information: current weather conditions, detailed forecasts, and useful charts to help you plan your day.

San Salvador, the capital of El Salvador, boasts a tropical climate characterized by warm weather throughout the year. Average annual temperatures fluctuate slightly, remaining in a comfortable range from 25°C to 27°C. This means travellers can expect warm days and pleasant evenings regardless of the time of their visit.

In San Salvador, two main seasons are clearly distinguished: the dry season and the rainy season. The dry season generally lasts from November to April. During these months, rainfall is minimal, and days are predominantly sunny, making this time ideal for excursions and outdoor activities. February and March are particularly dry, with practically no precipitation.

The rainy season usually begins in May and continues until October. During this period, the amount of precipitation and the number of rainy days increase significantly, reaching a peak in June and September. Rains most often occur in the afternoon or evening, characterized by short but intense showers. Despite the rain, the air temperature remains high.

The temperature regime in San Salvador is distinguished by pleasant stability throughout the year, although some characteristic features can be highlighted. Average monthly temperatures fluctuate within a rather narrow range: from approximately 25.3°C, observed in October and November, to 27.4°C, which are typical for March and April. Thus, it is March and April that can be considered the hottest months of the year, when the daytime air temperature regularly rises above 32°C, and in March can reach 33.2°C. The "coolest" months, if one can say so regarding a tropical climate, are October and November, but even at this time, average indicators remain very comfortable for travel.

If we examine the annual dynamics in more detail, we can note that during the dry season (approximately from November to April), daytime temperatures gradually increase. During this period, especially from January to March, the most significant daily temperature fluctuations are observed: daytime highs can exceed 31-33°C, while nighttime lows drop to 20-21°C, creating a difference of more than 10-12°C. With the onset of the rainy season (from May to October), the general air temperature remains high; however, daytime peaks become slightly less pronounced, usually staying within 29-31°C. Nighttime temperatures during this period are also slightly higher, around 22-23°C, resulting in a decrease in the daily temperature range to 7-9°C. Overall, the weather in San Salvador remains warm and conducive to relaxation all year round.

In San Salvador, a distinct seasonality in the distribution of precipitation is observed throughout the year. The dry season, covering the period from November to April, is characterized by a minimal amount of rain. The months from December to March are particularly arid, when the average monthly rainfall is 0 mm. For example, in January, February, and December, there are practically no rainy days (0-2 days), making this time ideal for those who prefer sunny weather without precipitation.

From May to October, the rainy season sets in San Salvador. During this period, precipitation levels and the number of rainy days increase significantly. The peak of rains falls in June, when an average of 12 mm of precipitation falls, and September, which is the "wettest" month in terms of the number of rainy days — a whole 29 days with precipitation and 10 mm of rain. In other months of this season, such as May, July, August, and October, a large number of rainy days (from 22 to 27 days) and a moderate amount of precipitation (from 6 to 8 mm) are also observed. Rains at this time generally have the character of tropical downpours, often intense but short-lived.

Transitional months also demonstrate characteristic features. April (2 mm of precipitation, 16 rainy days) signals the approach of the wet season with an increase in rain frequency, although their intensity is not yet high. November (3 mm of precipitation, 13 rainy days) marks the end of the rainy season and a gradual transition to drier weather. Overall, when planning a trip to San Salvador, it is worth considering these seasonal fluctuations in the nature of precipitation.

When packing your suitcase for a trip to San Salvador, plan for a tropical climate with warm weather year-round. The basis of your wardrobe should be light, breathable clothing made from natural fabrics such as cotton or linen. Shorts, T-shirts, light dresses, and skirts will be appropriate at any time. Given the high daytime temperatures, especially from January to April when the thermometer can rise above 32°C, do not forget a hat and sunglasses. In the evening, the temperature drops slightly but remains comfortable, so a light cardigan or wrap may come in handy, especially if you are sensitive to a light breeze or indoor air conditioning.

Particular attention should be paid to choosing clothes depending on the season. The dry season (from November to April) will delight you with plenty of sun and minimal rainfall, so feel free to take more summer items. However, from May to October comes the rainy season. During this period, especially in June and September when the number of rainy days reaches its maximum, you will need a light raincoat or a compact umbrella. Despite frequent rains, they are usually short-lived, and the air temperature remains high, so heavy waterproof items will not be required. Regardless of the season, be sure to bring comfortable shoes for walking around the city and sightseeing, as well as sunscreen with high SPF, as the sun in El Salvador is very active.

The principle of layering can be useful, especially if you plan to visit air-conditioned places or go on excursions to mountain areas where the temperature may be slightly lower. A light cardigan, thin sweater, or pashmina will not take up much space in your luggage but will add comfort. Don't forget insect repellent, especially if you intend to spend time outdoors or in the evening. And, of course, leave some space in your suitcase for souvenirs from hospitable San Salvador!
